Specification of Letters Patent.

Patented May 7, 1907.

Application filed April 11,1906. Serial No. 311,151.

To aZZ whom it may concern:

Be it known that I, JEROME L. BEARD, a citizen of the UnitedStatesgresiding -at Victor, in the county of Teller and State ofColorado, have invented fcertain new and useful Improvements inPipe-Cutters, of which the following is a specification. t 'rhisinvention relates to a tool for cutting pipe and consists of the novelfeatures, details of constructions and combinations of parts whichhereinafter will be more particularly set forth, illustrated andfinallyclaimed.

In the accompany drawings forming a part of the specifications: Figure 1is a side elevation of a pipe cutter embodying the invention. Fig. 2 isa perspective view of the de tachable shoe. Fig. 3 is a perspective viewof the block. Fig. 4 is a perspective view of the movable jaw.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The stock or body portion of the combined pipe Wrench and cuttercomprises a shank 1 which preferably has a uniform cross sectionthroughout and which is provided at one end with a laterally extendingfixed jaw 2. It will be observed that the inner face of the fixed jaw 2is depressed or curved inwardly and is provided with teeth 3 which arepreferably inclined. One side of the shank 1 is also provided with teethor serrations 4 by means of which an interlocking connection is obtainedwith the movable jaw 5. The movable jaw 5 is provided upon one side witha series of teeth 6 which are adapted to engage with the teeth 4 u onthe shank l, and is formed with a pair of spaced keepers by means ofwhich the movable jaw is slidably mounted upon the shank. In either casethe movable jaw 5 can be locked in a fixed position by means of a setscrew 8 passing through one of the keepers 7 and engaging with theshank 1. A shoe 10 is fitted over the fixed jaw 2, the said shoe beingformed with a longitudinal slot 11 having a pair of pipe cutting disks12 mounted therein.

One end of the shoe 10 is formed with a collar 13 which fits upon theshank 1 and a set screw 14 passes through the collar and engages withthe shank so as to lock the shoe rigidly in position. Each side of theshoe 10 isgalso provided with a pair of diverging arms 15 which embracethe fixed jaw 2. It may also be pointed out that the portion of the shoe10 fitting against the fixed jaw 2 is formed with teeth or serrations 16corresponding to the teeth 3.

The movable jaw 5 has its inner face notched at 17 and the removable ipeengaging member 9 is in the form of a b ock having grooves 18 onopposite sides thereof by means of which it is slidably mounted in thenotch 17 This block is provided with a pipe cutting disk 19 and isadapted to be forced inward as the cutting operation proceeds by meansof the adjusting screw 20 which passes through the movable jaw 5 andbears against the base of the member 9. In this instance, both of thekeepers 7 are preferably provided with set screws similar to the setscrew 8, and it will be apparent that when the movable jaw has beenmoved into engagement with the pipe, it can be locked in that positionby tightening the set screws so as to I draw the teeth 6 upon themovable jaw into engagement with the rack 4 upon the shank.

Having thus described the invention, what is claimed as new is: I

1. In combination a shank provided with a fixed jaw, a movable jawmounted upon the shank and adapted to be secured thereon at an adjustedposition, said movable jaw having a notch in its inner face, a blocksnugly fitting the recess of the movable jaw and having grooves inopposite ends to receive portions of the jaw bordering upon the recess,a cutter mounted upon said block and a set screw mounted in a threadopening of the movable jaw and adapted to advance the block and thecutter thereby.

2. In combination a shank provided with a fixed jaw having its innerface concave and toothed, a shoe adapted to snugly fit the concave faceand provided with matching teeth and with a collar to receive the shank,and provided with pairs of diverged arms to embrace opposite sides ofthe fixed jaw, a movable jaw mounted upon the shank and adapt- Intestimony whereof I affix my signature ed to be secured thereon at anadjusted poin presence of two Witnesses.

sition, said movable jaw having a recess, a block fitted in said recess,a set screw threaded'in the movable jaw and ada ted to advance theblock, and cutters fitte to the aforesaid shoe and block.
